new and useful Im rovements in Flushin Tanks for 1Water-C osets, of which the fo lowing is a specification.

My invention relates to improvements in flushing-tanks for water-closets, and con.-

sists of the novel arrangement, construction, and combination of parts, as will be fully hereinafter described and claimed.

.The object of my invention is to construct a tank composed of sheet metal, the outer portion being enameled and the inside of the tank provided with a lining of non-corrodible material.

In the drawings, Figure 1 is' a perspective view of my complete tank. Fig. 2 is a verlocked, forming a crimped ed e to prevent the use of rivets, solder, or t e like. The bottom 7 of the tank is also connected to the walls. of the tank by means of the edges being interlocked and crimped, as shown by the numeral 8. The outer surface of the tank and also the bottom is provided with an enameled surface 9 to give it the ap earance of china or earthenware, as may be esired, and in the inside of the tank I provide a lining 10, made of copper, zinc, or such material that will not corrode by the excessive use of water within. At the top and in the center of the tank I provide a cross-bar 11, rovided with a threaded stud 12, over whic is fitted the cover 13 and held in osition thereon. by eing screwed down upon the threaded stud 12. The tank is provlded with suitable valves for the admission and discharge of the water and the usual le- Specification of Letters Patent.

ver mechanism for 0 crating the same, the construction of whic I do not desire to cover by this application. The tank is held in position against the wall b assing screws through then per portion of the rear wall of the tank. T e most important feature in constructing a tank in this manner is to make a durable and neat-appearing device, as well as constructing it of a light material, which roves an'important item in shipping the tan I have found by practical experience, being in the plumbing-su ply business, that the tanks now constructed are made of earthenware and are exceedingly heav and some being made of cast-iron, which a so are very heavy, and in shipping such tanks at any distance the expense for same is very high, and in the earthenware tanks many become cracked or broken. p

In constructing a tank of. this character there is not a rivet used, but the edges in forming same are interlocked and securely crimped to ether, the outer surface then being coate with enamel, and the edges formed by the interlocking ends are completely covered with this enamel, which prevents leakage, yet by inserting the lining water is prevented from coming in contact with the outer section of the tank.

Having thus described my invention, what I claim as new, and desire to have secured to me by the grant of Letters Patent; is

A tank of the class described, comprising an outer casing formed by interlocking their edges, a bottom secured to the outer casing, the edges interlocked with the edge of the casing, the outer surface of the casin and bottom covered with enamel, a linin 0 noncorrodible material located within t e outer casing, a bar located at the top of the casing and provided with a threaded stud, and a cover located upon the casing and held in-position thereon by a nut secured to the threaded trunnion, substantially as specified.

In testimony whereof I have signed my name to thisspecification in presence of two subscribing witnesses.
